CSE 140L Hardware Lab Two |
||
| Objective |
In this lab, you will build 8-bit ripple adder/subtractor, 8-bit carry-lookahead adder, and 8-bit carry-select adder.
|
|
| Part 1 |
8-bit Adder/Subtractor with Overflow
Build a 8-bit Ripple Adder/Subtractor with Overflow Indicator. For negative numbers, use 2's compliment representation. Build this circuit and demonstrate the simulation to the TA. |
|
| Part 2 |
8-bit Carry Lookahead Adder
Build a 8-bit carry lookahead adder. Carry lookahead adder is an improvement over the ripple adder. Its purpose is to improve the speed of the adder by shortening the critical path. Build an 8-bit adder with 2 4-bit lookahead adders. Build this circuit and demonstrate the simulation to the TA. |
|
| Part 3 |
8-bit Carry Select Adder
Build an 8-bit carry select adder. Carry select adder is another way to improve the adder circuit by duplicating the amount of hardware. Build an 8-bit select adder by adding one more 4-bit carry lookahead adder in part 2. Build this circuit and demonstrate the simulation to the TA. |
